I have this question: $q_1$ is a Uniformly Charged long Wire(inf in z axis) with $\lambda$ (charge per unit length).
In (0,0,0) I have A very long conducting cylinder of radius a (also inf in z axis). NOT GROUNDED!!!
I want to find the electric potential everywhere. Where do i start? thanks!

Is there a pre-existing charge on the cylinder? –  Jim May 8 '13 at 14:55
    
no, the cylinder is neutral. –  Eli May 8 '13 at 14:58

I would recommend image charges, that should work rather well in this case. See here en.wikipedia.org/wiki/Method_of_image_charges. –  Noldig May 8 '13 at 15:04
    
hi Noldig! your suggestion is very helpfull when the cylinder is GROUNDED, but in this case the cylinder is NOT GROUNDED. –  Eli May 8 '13 at 15:07
    
@Eli: Plz see question again have they anywhere defined zero potential? NO. So, just define zero potential on the cylinder and calculate potentials of other space using Method of Images. –  Mr.ØØ7 May 8 '13 at 15:55
